Abstract: Few ecosystem restoration studies monitor arthropods as important components of ecosystem recovery. We tested the hypothesis that ponderosa pine restoration treatments would increase adult butterfly species richness and abundance by monitoring changes in butterfly abundance following restoration. To examine potential mechanisms of adult butterfly distribution, the host plant availability, nectar plant availability and insolation (light intensity) were sampled in restoration treatment units and control forests. Three patterns emerged: 1. Butterfly species richness and abundance were 2 and 3 times greater, respectively, in restoration treatment units than in paired control forests one year following treatment, and 1.5 and 3.5 times greater two years following treatment. 2. Host plant and nectar plant species richness showed little difference between treated and control forests even 2 years following treatment. 3. Insolation (light intensity) was significantly greater in treated forests following restoration.
